Table 5.

Estimated odds ratios and 95% confidence intervals for the association of individual cognitive biases with intent to vaccinate (N = 1400).

Variable	OR	95% CI
Base Rate Neglect	0.99	0.77	1.26
Conjunction Fallacy	0.90	0.69	1.18
Sunk Cost Bias	1.02	0.80	1.30
Information Avoidance	0.76	0.60	0.96
Present Bias	1.20	0.77	1.88
Risk Aversion	0.85	0.66	1.09

Note: Cognitive biases were coded dichotomously (Susceptible to bias vs. not susceptible); the OR indicates the odds of intending to vaccinate if the bias is present vs if the bias is absent.
